I’m having an issue installing my TestFlight build on a Mac. The build (v1.0 build 1) uploads successfully and shows as “Complete” in App Store Connect. I can also open the build details page, and my Apple ID / tester access / group setup looks correct.

However, on TestFlight (macOS), when I tap Install/Load, I get this error: Unable to install. The requested app isn’t available or can’t be found.

Notes: The app is an iOS app (iPhone + iPad), and I enabled availability for Mac (Designed for iPad) in App Store Connect. The Mac is Apple Silicon, running macOS Tahoe 26.1.

Could you help me understand why TestFlight shows this message on Mac, and what I should change in Xcode/App Store Connect to make the build compatible?

Thanks for the post. I believe the issue you're encountering stems from attempting to install an iOS app build, even though it's marked as "Designed for iPad," on a Mac. While Apple Silicon Macs can run iOS and iPadOS apps natively, there are nuances in TestFlight's handling of these builds that might cause installation issues if not configured correctly. I am not in the TestFlight team so I need to make sure this is the most accurate answer, I have invited the TestFlight team to post their answer in this thread however, they are not actively monitoring the forums.

To make sure, ensure that the build settings in Xcode explicitly support macOS as a destination under "Supported Destinations" or via Universal Control settings for Apple Silicon. Open your Xcode project. Navigate to your target settings, and under the "General" tab, ensure that "Deployment Info" specifies iOS as the platform. For Universal apps, make sure "Supported Destinations" includes "My Mac (Designed for iPad)" if you specifically intend to run it as such.

By ensuring your app’s build settings and App Store Connect configurations align with macOS’s support for running iOS apps, you should be able to resolve installation issues. Given that this involves a beta OS, staying updated with the latest macOS and Xcode patches is also crucial, as they might address underlying compatibility glitches.
